Method and device for displaying target object

1. A method for displaying objects, applicable to an electronic device and comprising: detecting, in pieces of video data to be displayed in a first display region, if there are video frames that contain objects of predefined types; if video frames that contain objects of the predefined types are detected, extracting the objects of the predefined types from the detected video frames; and displaying the extracted objects in sub-regions of a second display region that is different from the first display region, with each object being displayed in one of the sub-regions, wherein extracting the objects of the predefined types from the detected video frames, comprises: extracting objects of the predefined types that are different from reference objects from the detected video frames, wherein the reference objects are of the predefined types and are extracted from previously detected video frames, wherein displaying the extracted objects in sub-regions of a second display region, comprises: arranging the extracted objects in a sequence according to a predefined rule; and displaying the objects in the sub-regions of the second display region according to the sequence; wherein after displaying the extracted objects in sub-regions of a second display region, the method further comprises: obtaining an object selection instruction comprising a target type for a selected object, wherein the selected object is one of the extracted objects, and the target type is selected from one of the preset types; identifying objects of other types than the target type from the extracted objects being displayed in the second display region according to the object selection instruction; and removing the objects of other types from the second display region; and wherein after displaying the extracted objects in sub-regions of a second display region, the method further comprises: obtaining a video playback instruction for a third object; determining video data for the third object, which contains video frames having the third object; and playing back the determined video data in a third display region.

2. The method of claim 1 , wherein detecting, in pieces of video data to be displayed in a first display region, if there are video frames that contain objects of predefined types, comprises: performing object detection for objects of the predefined types to video frames in the pieces of video data to be displayed in the first display region; and determining, based on a result of the object detection, if there are video frames that contain the objects of the predefined types.

3. The method of claim 2 , wherein before performing object detection for objects of the predefined types to video frames in the pieces of video data to be displayed in the first display region, the method further comprises: determining if the object detection for objects of the predefined types is supported by video acquisition devices that acquired the pieces of video data; and if not supported, performing the object detection for objects of the predefined types to video frames in the pieces of video data to be displayed in the first display region.

4. The method of claim 3 , further comprising: if the video acquisition devices support the object detection, determining if there are video frames that contain the objects of the predefined types, according to a result of the object detection for objects of the predefined types performed by the video acquisition devices to video frames in the pieces of video data to be displayed in the first display region.

5. The method of claim 1 , wherein the sub-regions of the second display region are longitudinally distributed; and displaying the objects in the sub-regions of the second display region according to the sequence, comprises: displaying the objects from bottom to top in the sub-regions of the second display region according to the sequence; determining if any of the extracted objects has not been displayed in the sub-regions; and if so, removing a first object in the lowest sub-region, sequentially moving other displayed objects than the first object into respective sub-regions adjacently below, displaying an object, that has not been displayed, in the uppermost sub-region, and proceeding back to determination as to if any of the extracted objects has not been displayed in the sub-regions; or wherein, the sub-regions of the second display region are transversely distributed; and displaying the objects in the sub-regions of the second display region according to the sequence comprises: displaying the objects from left to right in the sub-regions of the second display region according to the sequence; determining if any of the extracted objects has not been displayed in the sub-regions; and if so, removing a second object in the leftmost sub-region, sequentially moving other displayed objects than the second object into respective sub-regions adjacently on the left, displaying an object, that has not been displayed, in the rightmost sub-region, and proceeding back to the determination as to if any of the extracted objects has not been displayed in the sub-regions.

6. The method of claim 1 , wherein after displaying the extracted objects in sub-regions of a second display region, the method further comprises: determining information about video acquisition devices for the objects; and displaying the information about the video acquisition devices for the objects in corresponding sub-regions that are displaying the objects.

7. An electronic device, comprising a processor, a communication interface, a memory, and a communication bus, wherein the processor, the communication interface, and the memory communicate with each other via the communication bus; the memory is configured for storing a computer program; and the processor is configured for executing the program stored on the memory to carry out the method of claim 1 .

8. A non-transitory computer readable storage medium having a computer program stored thereon which, when being executed by a processor, performs the method of claim 1 .
